Petroleum
What is Petroleum?
Petroleum, commonly referred to as petrolatum or petroleum jelly, is derived from crude oil via distillation, dewaxing, and extensive purification to yield a stable, inert semi-solid. Chemically, it consists of long-chain saturated hydrocarbons, mainly branched and unbranched alkanes with minimal aromatic content in cosmetic grades. It belongs to the emollient and occlusive category in cosmetics, appearing in lip balms, healing ointments, cold creams, and protective lotions. In formulations, it works by creating a hydrophobic film over the skin surface, reducing evaporation of water and aiding in skin barrier repair without penetrating deeply. This property suits it for use on chapped lips, minor cuts, or extremely dry areas. Cosmetic-grade versions undergo rigorous refining to meet purity standards set by regulators.
